INDIANA, A CORPORATION OF DISK FOR SPEED-VARYING MECHANISMS.

SPECIFICATION forming part of Letters Patent No. 761,910, dated June 7, 1904.

Application filed December 21, 1903. Serial No.186,123. (No model.)

To a, whom it may concern.-

Be it known that I, MILTON O. REE ES, a citizen of the United States, residing at Columbus, in thecounty of Bartholomew and State of Indiana, have invented certain new and useful Improvements in Disks for Speed-Varying Mechanisms, of which the following is a specification.

In speed-varying mechanisms of .the type shown in my Patent No. 603,067, issued to the Reeves Pulley Company April 26, 1898, diificulty has been experienced by reason of the creeping of oil, used to lubricate the shafts upon which the disks are carried, outward upon the belt-friction coned face of the disks; and the object of my invention is to producea construction of disks which will prevent this action.

The accompanying drawings illustrate my invention. v

Figure 1 is a central axial section of a disk for use in speed-varying mechanisms of-the type mentioned, and Fig. 2 is a section on line 2 2 of Fig. 1. V

In the drawings, indicates the hub Of the disk 11, which hub is bored to receive a shaft 12. The working face 13 of the disk 11 has formed therein an annular pocket 14:, the in forated, as at 18, to permit the withdrawal of oil which it may accumulate in the chamber 16.

In operation any surplus of oil on the shaft 12 will creep out over lip 15 and thence by Formed back of the workreason of centrifugal force pass outward along the inner wall of chamber 14 and from thence through hole 17 into chamber 16, thus preventing any possibility of the surplus oil passing onto surface 13.

I claim as my invention 1. A rotating disk having an axial bore and a working face at an angle to said bore, and a pocket formed beneath the working face of the disk. and having its point of junction with the bore isolated from said working face, for the purpose set forth.

2. A rotating disk having an axial bore and a working face at an angle to said bore, an annular pocket formed beneath the working face of the disk and having its point of junction with the bore isolated from said working face, and an outlet leading from said pocket away from the working face of the disk.

3. A rotating disk having an axial bore and a working face at an angle to said bore, an annular pocket formed beneath the working face of the disk and having its point of junction with the bore isolated from said working face, an oil-receiving chamber formed at the back. of the disk, and passages leading from the annular pocket to the oil-receiving chamber.

1. A rotating disk having a face at an angle to the axis of rotation, and an annular oil-receiving pocket formed beneath the said face of the disk around the axis of rotation. V

In,witness whereof I have hereunto set my hand and seal, at Columbus, Indiana, this 7th "day of December, A. D. 1903.
